Much like a campiello, a campazzo is an open space that does not usually contain a church or any wells. Physically, it very much similar to a campiello or a campo, the slight difference lying mainly in historical uses and definitions. In the earlier years of Venice, before the islands had as many buildings as they do today, the campi were grassy fields located in various parts of the city. Campazzo was used as a term to refer to campi that were untended and overgrown.
There are not many campazzi found in Venice, but an example of such space is Campazzo San Sebastiano. This campo serves as a midway campo that connects Campo San Sebastiano and Campo dell'Angelo Raffaele.
